MACHINE FOR FEEDING PAPER TO PRINTING-PRESSES.

Specification of Letters Patent No. 12,761, dated April 24, 1855.

To all whom t may concern Be it known that we, ISAAC B. LIVINGSTON and MILES VVATERHOUSE., of Barnet, in the county of Caledonia and State of Vermont, have invented a new and useful Machine for Feeding Paper to Printing-Presses; and we do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, refer'- ence being had to the annexed drawings, making a part of this specification, in which- Figure l is a perspect-ive view. Fig. 2 a ground plan of machinery for raising the paper table, Fig. 3 a view of one of the angular guide ways.

A, A, is the bed plate. tached to said plate.

C is an exhausting apparatus as a bellows or air pump or their equivalents.

D, D, are tubes attached to the exhausting apparatus, these tubes to be made of any suitable material.

E, is a crossbar attached to the tubes near their lower end to retain them at their proper distance from each other, and having each end fitted so as to move in the angular guide ways.

F, F, are angular guide ways in which the end of crossbar E moves and are attached to sides B, B.

G, Gr, are levers attached to crossbar E, the other ends are att-ached to two sliding boxes by a pivot on which they vibrate.

H, H, are the sliding boxes to which the levers G, G, are attached.

I, I, are parallel ways on which the boxes H, H, slide.

a a. are arms of peculiar construction attached to levers G, G, between which the crank K operates to push forward, fetch back, and raise up said levers. l

K is a compound crank, one part Working between arms a. a the other operates the exhausting apparatus C.

b, is a crosshead attached to top of exhausting apparatus as a bellows or piston to pump.

C, C, are connecting rods, connecting crank K, with the cross head b.

N (Fig. 2) is the driving shaft, having spur gear lV, which meshes into the intermediate S, and has a bevel gear at or near the other end.

M lis a shaft driven by shaft N, by bevel gear and having a screw at the other end.

B, B, sides at- L is a shaft having bevel gears at each end, and spur gear in center in which the screw on shaft M works.

g, g, are shafts to which cams f, f, f, f, are attached, and are worked by shaft L, being connected with it by bevel gears.

R, is a table resting upon the cams j', f, f, f, upon which the paper is laid, and which is raised by machinery described so as to keep the paper to proper height for the tubes.

Operation: By turning crank m you give motion to shaft N, which is geared by the intermediate cog wheels to crank shaft K, working between the arms a, a., attached to levers G, G, the crank K first strikes the top of the arm a which raises it and the lever and its attachments to its highest pointand continuing its stroke presses against the side of arm a, throwing or pushing t-he levers G, G, with tubes, and crossbar attached forward to the required distance along the guide ways F, F. K, K, is crank attached to the exhausting apparatus at about right angles with crank K, so that when the levers have been raised, and carried forward to the required point the exhausting apparatus shall blow of the paper which was attached to the tubes, and when the crank K, has pushed back the lever Gr, G, and allowed the tubes D, D, to drop upon the paper the crank K, will commence to operate the exhausting apparatus so as to exhaust the air from the tubes D, D, which causes the paper to adhere to them by suction or atmospheric pressure the crank K, in the meantime has passed to top of arm a, raising the levers G, G, and their attachments and carrying them forward as described. At the same time the ream of paper has been raised the distance of the thickness of that of paper by its machinery, viz: The shaft N, is driven by crank X, and by bevel gear drives the shaft M, the screw on shaft M, drives spur gear on shaft L which by the bevel gear at each end moves the shafts g, g, and with them the cams f, f, f, f, and the table R, resting upon the face ofthe cams will be raised by them to the distance required.

What we claim as our invention and wish to secure by Letters Patent is l. We claim the use of the angular guide ways in combination with the crossbar or its equivalent.

2. fWe claim the use of crank or its equivalent working between the arms of levers as described, in combination with levers and But- We do claim the combination of mal0 crossbar as described. chinery as described for carrying forward 3. We claim the raising table in oombinathe paper a sheet at a time and feeding it to tion with the cams shafting and gearing printing presses.

5 (for moving said tab1e,) or their equivalents ISAAC B. LIVINGSTON.

as described. MILES VATERHOUSE.

4. We do not claim the raising of paper In presence ofby atmospheric pressure as that has been be- J. A. JOHNSON,
